I don't like double posting, but I found out something interesting and I have to share. ABUS use key pins very similar to these in some of their cylinders as a counter measure against bumping.
I think the idea is to dissipate some of the energy so the drivers don't jump as much. Doesn't make it bump proof, but it does make it more difficult. I think coupled with the balanced drivers in this, they'd do a pretty good job... I'd test it to find out, but I don't wanna put bump keys anywhere near this beauty.
